2 friends in Russia did the impossible. For whatever reason, they decided to turn their kitchen into a swimming pool full of water, and then empty all the water down into the basement.
Vladimir Vechnyy and his friends did this on the ground floor of a flat in city of Tver in western Russia’s Tver Oblast region by covering the floor and walls with plastic sheets which they glued together to create a waterproof seal.
The cat even got into it… maybe. haha
